WINDOW MOUNTING.

Application led July 21, 1924. vSerial No. 727,265.

lt is an object of the invention to provide a mounting for the sliding sashes of a win .dow which will combine in a unitary mem ber both a hinged and slidable support for s the sash permitting the latter to be raised and lowered and to be swung inwardly without interference one with the other.

The invention further consists in certain structural features of formation of the hinge member adapting it to establish a sliding engagement with a guide member.

A preferred embodiment of the invention is illustrated in the accompanying drawings, in which,

Figure 1 is a view in interior elevation of a window equipped with the improved mounting, in which the sashes are shown in their normally closed positions.

Figure 2 is a perspective view of one of the hinge members of the lower sash, detached.

Figure 3 is a vertical sectional view taken on line 3 3 of Figure 1.

Figure 4 is a transverse sectional view through the upper sash with the lower sash shown in plan, both sashes being swung inwardly at right. angles to their normal positions. s

Figure 5 is a sectional detail view taken on line 5--5 of Figure 4, showing primarily a provision for attaching the counterbalance cord to one of the hinge members.

In these views the reference characters 1 and 2 designate respectively the upper and lower sashes of the window, and 3 and 4 indicate the side jambs of the window frame. Mounted upon the j amb 3 are two adjacent channel-shaped guides 5, preferably of sheetmetal, extending, one opposite to each sash the full height of the window opening. Said guides have spaced inward extensions 6= from the edges of their side walls, and are secured to the jamb 3 by screws 7.

Each of the sashes has secured upon one edge thereof the leaves 8 of a pair of spaced hinges 9, the complementary leaf 10 of each hinge being'v formed to slidably engage a corresponding channel guide and thus adapt said hinges to establish both ay pivot support and a slidable mounting for the sash.

The slidable engagement between the channel guide 5 and the complementary leaf 10 of the hinge is established by forming in oppositeedges of said leaf opposed recesses or channels 11 for receiving freelythe respective flanges G of said channel guide to retain the )arts against lateral dis olacement, yet slidably interengaged, as clearly shown in Figure 4.

It will be understood that the pivotal engagementv for the sashes is established by the pins 12 of the hinges and in order that both sashes may at the same time be swung to positions transverse to the frame of the window without interfering with each other, both leaves of eachhinge are intermediately bent at a right angle, and the hinges of the respective sashes are oppositely positioned, so that the pins 12 of the hinges ofthe upper sash arev offset away from the jamb` 3, while those of the. lower sash hinges are oliset toward said jamb and disposed relatively close thereto. The position of the sashes as shown in Figure 4 is permitted by the described location ofthe hinge pins,

.A suitable stop strip 13, secured to the j amb 4, forms an outer guide for the upper sash. The two sashes overlap each other suiiiciently in their normally closed positions to prevent inward` swinging of said upper sash andthel lower sash may beheld against inward swinging by any suitable releasable means, such as a removable stop strip or latchv (not shown).

Each sash may be counterbalanced by a weight 14 suspended by a cord 15 passing over a pulley 16 jcurnaled in the upper end of the jamb 3. The attachment of said cords to the sashes is effected preferably by forming the upperleaflO of each sash with an integral hook or the like 17 to detachably receive eyes or loops on said cords.

It will be observed that by the described construction the hinge as a unit serves to establish a direct connection between the sash cord and sash as well as a pivotal and slidable connection between the sash and channel guide, eliminating all intermediate t rsvaesii manu facture.

Vhat I claim is: l

l. In a Window construction, the co1nbination With a :trame having a Window opening, of a channel guide mounted upon said frame Within said opening and formed with `a pairl of opposed flanges, a closure for said openi110*y and .a hinge coin iisino a leaf securedV b5 E3 C to said closure, and `a complementary leaf having 4a poition of increased thickness, the opposite edges of` `which are giooved for sliding engagement With said flanges.

2. In a Window construction, the eomhina- Y tion with a frame having a Window opening, of a channel guide mounted upon said frame Within said opening and formed with a paii1 of opposed flanges, a closure for said opening7 and a hinge vcomprising a leaf secured to said closure', and a complementary leaff hent to form substantially a right angle7 and increasedy in thickness `at one s'ide of said angle,` and groovedupon opposite edges for sliding engagement with said flanges, and a pojection from said giooved `portion into said channel Guide for enfafeinent h `a b b b counter-balance Gerd.v v

In testnneny whereof I sign this Specification. l
